you're all belted in and this thing is part of the rim right here, it's gonna whirl round, round, round. now what would happen if you sat in a chair like that, belted in? back, of course, your head. you don't want your neck to break. what would happen if they boost it up till you're going like speeds near the speed of light? would you be comfortable or a little bit nauseous? honey, you would be dead, okay? you'd be splattered all over that thing, right? centrifugal force, okay? you wouldn't make it, you wouldn't make it. the acceleration would be too enormous. but let's make believe, let's make believe you could sit in the centrifuge and go up to the speeds near the speed of light without getting killed. just make believe, okay? what might happen? it might go like this, they say to you, okay, here's a little red button down here. when you get tired, for any reason you want us to stop, hit the red button, outside, the alarm will sound and when the alarm sounds, we'll cut down the electricity and that'll bring it down to a stop, open it up and see how you're doing. you are the first one to try this, so good luck. so they go out, they close door, they get you belted in.
